Speaking at ISBA's annual lunch yesterday, in conversation with the advertiser body’s director general Phil Smith, Sadoun discussed topics ranging from trust through to the Marcel project.

On the controversial AI initiative, Sadoun stressed that the move was about transformation and claimed he did not mind if he lost his job because of his attempts to change things.

"I’m happy to get fired, I don’t care, I have other things to do," he said.

Sadoun garnered applause when he said of the criticism: "I'll take it, I don't care."

But he also said he was "a bit sad to see… something that could be a game changer has been in the shadow of this big issue about the festival".

Sadoun identified staff retention as one of the main reasons behind Marcel, citing research showing that 40% of people in the industry wanted to leave in the next two years.

"We want to make sure that any of our employees could have the best opportunities when it comes to a creative brief, when it comes to learning, when it comes to shine."

The young generation, Sadoun said, "want to be recognised quite quickly; they want to make things, they want to be engaged, they want to be able to touch different things in a different way".

He told the story of how a difficult French client called up after hearing about the news from Cannes and said: "Hey Arthur, I was going to fire you but it seems like you’re making progress so I’m going to give you six months more."

Need for change

Sadoun took aim at bigger network rivals WPP and Omnicom for not changing their "architecture" in the last 20 years: "We are not putting technology at the core, we are the only service industry that hasn’t tried," he claimed. "You can’t fix those big challenges if you don’t bring the right level of transformation."

Brand trust was the "biggest battle of our industry". "Restoring the trust between agencies and clients is a top priority," Sadoun added.

Power of One

During the event hosted in a packed room at the Dorchester, Sadoun turned to the Publicis Power of One philosophy which is based on breaking down silos between agency brands. To illustrate how it was working in practice, he pointed out that Leo Burnett creatives in Sao Paulo were going to work on Super Bowl ads with Saatchi & Saatchi in New York.
